I have a soft spot in my heart for Autozone... I can remember two specific tools I needed in a pinch and they were the only place that I could find that carried them at the time: T-70 Torx bit for trans fluid changes and an O2 sensor socket. They also have a pretty sweet tool rental program: pay deposit, borrow tool, use tool, return tool, get deposit back. I usually end up there when Pep Boys or Advance Auto don't have what I'm looking for. Pep Boys definitely gets the prize for having a whole section devoted to colorful, chrome, and/or fake carbon fiber ricey bits

^ I worked at a Pep Boys about 12-14 years ago. I was in charge of that isle,hahahahaha, It was new at the time and I drove a 91 Tsi. with a pace setter cat back. My intro to turbocharged cars! Also my intro to selling rice..haha
